Referring to FIGS. 1 and 2, the disclosure provides a curved display panel 400 including an active array substrate 410; a plurality of pixel units formed on the active array substrate 410, each of the pixel units including a plurality of monochromatic sub-pixel units 411 arranged in an array, the plurality of monochromatic sub-pixel unit 411 being different in color, the sub-pixel unit 411 being a rectangular structure, and a long side of the monochromatic sub-pixel unit 411 being parallel to a bending direction of the display panel 400; an opposite substrate 430 disposed opposite to the active array substrate 410; and spacers 440 disposed between the active array substrate 410 and the opposite substrate 430 so as to support the active array substrate 410 and the opposite substrate 430 when the external force is applied, and the distribution density of the spacer 440 being increased from middle of the display panel 400 toward both curved sides.

Specifically, the display panel 400 includes an active array substrate 410 and a opposite substrate 430 disposed opposite thereto. The active array substrate 410 includes a plurality of pixel units, each pixel unit includes a plurality of monochromatic sub-pixel units 411 arranged in an array. The plurality of monochromatic sub-pixel units 411 are different in color, the monochromatic sub-pixel unit 411 is a rectangular structure, and a long side of the monochromatic sub-pixel unit is parallel to a bending direction of the display panel, the size of the monochromatic sub-pixel unit 411 along the direction of the bending line of the display panel 400 is smaller than the size of the other directions of the monochromatic sub-pixel unit 411, that is, when the panel 400 is bent, the size of the monochromatic sub-pixel unit 411 in the direction of the bending line 450 of the panel 400 is the smallest size of the monochromatic sub-pixel unit 411.Take a liquid crystal display panel as an example, the liquid crystal layer 420 and the spacers 440 are disposed between the active array substrate 410 and the opposite substrate 430, the spacers 440 is used for supporting the active array substrate 410 and the opposite substrate 430 when external force is applied, and the distribution density of the spacers 440 is gradually increased from middle of the panel 400 toward both curved sides. Due to the bending of the panel 400, the internal stress of the panel 400 is gradually increased from the middle of the panel 400 toward both curved sides, the distribution density of the spacers 440 is increased correspondingly to counteract the partial stress of the different portions, that is, as shown in FIG. 2, in the three regions of a, b, and c, after the panel 400 is bent, the bending stress of the three regions is a>b>c, therefore the density of the spacers 440 in the three regions is distributed here to counteract the bending stress, specifically, the distribution density of the spacers 440 of the three regions is a>b>c.

By changing the arrangement of the monochromatic sub-pixel units 411 to make the smallest portion of the monochromatic sub-pixel units 411 on the bending line of the curved surface and changing the distribution density of the spacers 440 in the panel 400 to make the distribution density of the spacers 440 gradually increase from the middle of the panel 400 toward both curved sides, thereby area change of the monochromatic sub-pixel units 411 during bending is reduced, and the problem of unevenness of the cell thickness due to the large partial stress when both sides of the panel 400 are bent is improved, so that better picture quality of the display panel in the side view can also be achieved.

In some embodiments, the curved display panel may be, for example, a twisted nematic liquid crystal display panel, a planar conversion type liquid crystal display panel, a multi-quadrant vertical alignment type liquid crystal display panel, an OLED curved display panel, a QLED curved display panel, or others.

Specifically, the pixel unit includes a plurality of monochromatic sub-pixel units 411 different in color and arranged adjacent to each other along the direction of the bending line 450 of the display panel 400.

Specifically, each pixel unit consists of a plurality of monochromatic sub-pixel units 411, for example, it may consist of three monochromatic sub-pixel units 411, which are the sub-pixel monochromatic units 411 of R, G, B, respectively, and the three monochromatic sub-pixel units 411 are arranged adjacent to each other along the bending line 450.

Referring to FIG. 5, specifically, the monochromatic sub-pixel unit 411 is a rectangular structure, the long side of the rectangular structure is parallel to the bending direction of the panel 400, then the short side thereof is parallel to the bending line 450 of the panel; the size of the monochromatic sub-pixel unit 411 located on the portion of the bending line 450 is the smallest, thus the amount of deformation of the monochromatic sub-pixel unit 411 when the panel 400 is bent is the minimum.

Specifically, referring to FIGS. 6 and 7, FIGS. 6 and 7 are schematic diagrams of the monochromatic sub-pixel unit 411 in two different arrangements, a monochromatic sub-pixel unit 411 m shown in FIG. 6 is an arrangement used in the prior art, the size of the monochromatic sub-pixel unit 411 m in the x-axis direction is smaller than the size in the y-axis direction, the y-axis direction in the figure is the direction of the bending line of the panel 400. After the panel 400 is bent, the monochromatic sub-pixel units 411 m will get an amount of deformation in x-axis direction, as shown in the region Q1 of FIG. 6, thereby causing the pixel areas of the left and right sides in FIG. 6 to be asymmetric. The monochromatic sub-pixel unit 411 n shown in FIG. 7 is an arrangement used in the present embodiment, by rotating the existing designed pixel unit 90 degrees and then arranging, at this moment the size of the monochromatic sub-pixel unit 411 n on x-axis is larger than the size on the y-axis, the y-axis direction is the direction of the bending line of the panel 400. After the panel 400 is bent, the deformation region of the pixel unit in the x-axis direction is shown as Q2 in the figure; due to the same bending curvature of the panel 400, the deformation sizes of the deformation regions Q1 and Q2 on the x-axis are the same, but the size of the deformation region Q1 of the monochromatic sub-pixel unit 411 m on the y-axis is larger than the size of the deformation region Q2 of the monochromatic sub-pixel unit 411 n on the y-axis, so that the area of the deformation region Q2 is less than the area of the deformation region Q1, that is, after the panel 400 is bent, the amount of deformation caused by bending by the arrangement of the sub-pixel units 411 n used in the present embodiment is less than that by the arrangement of the sub-pixel units 411 m used in the prior art.

Further, the surface of the monochromatic sub-pixel unit 411 is etched with an alignment pattern, and the ratio between the alignment patterns is changed with the curvature of the display panel at a current position.

Referring to FIGS. 3, 4, and 5, specifically, for example, the monochromatic sub-pixel unit 411 is divided into two alignment patterns A and B; when the panel is plane, the area of alignment pattern A is equal to that of alignment pattern B, namely, as shown in FIG. 3, the area of the left and right alignment pattern regions on the three monochromatic sub-pixel units 411 a, 411 b, and 411 c at different positions are equal. When the panel 400 is bent, as shown in FIG. 4, under the bending stress, the areas of the left and right alignment patterns on the monochromatic pixel units 411 a, 411 b, and 411 c which should be the same have changed. In order to make the ratio between the alignment patterns on the monochromatic pixel unit 411 still reach the target ratio after the panel is bent, the ratio compensation is performed in advance when the panel 400 is in the planar state. For the monochromatic sub-pixel unit 411 a in the figure, deformation thereof occurs after the panel 400 is bent, the left alignment pattern region is smaller than the right alignment pattern region, namely, the left-side of the monochromatic sub-pixel unit may be compensated in advance in the planar state, so that the area of the left alignment pattern of the monochromatic sub-pixel unit 411 a is larger than the area of the right alignment pattern, so as to achieve the areas of the left and right alignment patterns of the monochromatic sub-pixel unit 411 a to be the same after the panel 400 is bent. For the monochromatic sub-pixel unit 411 c in the figure, deformation thereof occurs after the panel 400 is bent, the left alignment pattern region is larger than the right alignment pattern region, namely, the right-side monochromatic sub-pixel unit may be compensated in advance in the planar state, so that the area of the right alignment pattern of the monochromatic sub-pixel unit 411 c is larger than the area of the left alignment pattern, so as to achieve the areas of the left and right alignment patterns of the monochromatic sub-pixel unit 411 c to be the same after the panel 400 is bent.

The alignment pattern of the monochromatic sub-pixel unit 411 at each curvature position on the panel 400 should be preliminarily considered how it has deformed after bending, thus according to the amount of deformation of the monochromatic sub-pixel unit 411 at each curvature position after bending, the area of the alignment pattern of the monochromatic sub-pixel unit 411 in the planar state is compensated, so as to allow the ratio of the alignment pattern of the monochromatic sub-pixel unit 411 at each curvature position after the panel 400 is bent to reach the target ratio.

Referring to FIG. 1, furthermore, the spacer 440 includes a main body 441 and an auxiliary body 442, the height of the auxiliary body 442 is lower than the height of the main body 441, and the auxiliary body is disposed on the side of the main body 441, the hardness of the auxiliary body 442 is greater than the hardness of the main body 441.

Specifically, the spacer 440 includes the main body 441 and the auxiliary body 442, the height of the auxiliary body 442 is lower than the height of the main body 441, the auxiliary body 442 can assist in the support the active array substrate 410 and the opposite substrate 430 after the main body 441 reaches the limit of supporting; for example, the height of the auxiliary body 442 is two-thirds the height of the main body 441, simultaneously, the auxiliary body 442 is disposed on the side of the main body 441, when supporting the substrate, the section between the main body 441 and the auxiliary body 442 also plays a supporting role to improve the supporting ability of the spacers 440; in addition, in the selection of the material of the spacer 440, the main body 441 may use a conventional materials, and the material hardness of the auxiliary body 442 is greater than the material hardness of the main body 441.

Take a liquid crystal display panel as an example, the liquid crystal layer 420 is disposed between the active array substrate 410 and the opposite substrate 430, and spacers 440 is used for supporting the active array substrate 410 and the opposite substrate 430 when external force is applied, and the distribution density of the spacers 440 gradually increases from the middle of the panel 400 toward both curved sides. Due to the bending of the panel 400, the internal stress of the panel 400 is gradually increased from the middle of the panel 400 toward both curved sides, the distribution density of the spacers 440 is increased correspondingly to counteract the partial stress of the different parts, that is, as shown in FIG. 2, in the three regions of a, b, and c, after the panel 400 is bent, the bending stress of the three regions is a>b>c, therefore the density of the spacers 440 in the three regions is distributed here to counteract the bending stress, specifically, the distribution density of the spacers 440 of the three regions is a>b>c.

By changing the arrangement of the monochromatic sub-pixel units 411 to make the smallest portion of the monochromatic sub-pixel units 411 on the bending line of the curved surfaces and changing the distribution density of the spacers 440 in the panel 400 to make the distribution density of the spacers 440 gradually increase from the middle of the panel 400 toward both sides of the bending, thereby area change of the monochromatic sub-pixel units 411 during bending is reduced, and the problem of unevenness of the cell thickness due to the large partial stress when the both sides of the panel 400 are bent is improved, so that better picture quality of the display panel in the side view can also be achieved.

Specifically, the pixel unit includes a plurality of monochromatic sub-pixel units 411 different in color and arranged adjacent to each other along the direction of the bending line 450 of the display panel 400.

Specifically, each pixel unit consists of a plurality of monochromatic sub-pixel units 411, for example, it may consist of three monochromatic sub-pixel units 411, which are the sub-pixel monochromatic units 411 of R, G, B, respectively, and the three monochromatic sub-pixel units 411 are arranged adjacent to each other along the bending line 450.

Referring to FIG. 5, specifically, the monochromatic sub-pixel unit 411 is a rectangular structure, the long side of the rectangular structure is parallel to the bending direction of the panel 400, then the short side thereof is parallel to the bending line 450 of the panel; the size of the monochromatic sub-pixel unit 411 located on the portion of the bending line 450 is the smallest, thus the amount of deformation of the monochromatic sub-pixel unit 411 while the panel 400 is bent is the minimum.

Specifically, referring to FIGS. 6 and 7, FIGS. 6 and 7 are schematic diagrams of the monochromatic sub-pixel unit 411 in two different arrangements, the monochromatic sub-pixel unit 411 m shown in FIG. 6 is an arrangement used in the prior art, the size of the monochromatic sub-pixel unit 411 m in the x-axis direction is smaller than the size in the y-axis direction, the y-axis direction in the figure is the direction of the bending line of the panel 400; after the panel 400 is bent, the monochromatic sub-pixel units 411 m will get an amount of deformation in x-axis direction, as shown in the region Q1 of FIG. 6, thereby causing the pixel areas in the left and right sides of FIG. 6 to be asymmetric. The monochromatic sub-pixel unit 411 n shown in FIG. 7 is an arrangement used in the present embodiment, by rotating the existing designed pixel unit 90 degrees and then arranging, at this moment the size of the monochromatic sub-pixel unit 411 n on x-axis is larger than the size on the y-axis, the y-axis direction is the direction of the bending line of the panel 400. After the panel 400 is bent, the deformation region of the pixel unit in the x-axis direction is shown as Q2 in n the figure; due to the same bending curvature of the panel 400, the deformation size of the deformation regions Q1 and Q2 on the x-axis is the same, but the size of the deformation region Q1 of the monochromatic sub-pixel unit 411 m on the y-axis is larger than the size of the deformation region Q2 of the monochromatic sub-pixel unit 411 n on the y-axis, so that the area of the deformation region Q2 is less than the area of deformation region Q1, that is, after the panel 400 is bent, by adopting the arrangement of the sub-pixel units 411 n used in the present embodiment, the amount of deformation caused by bending is less than that by the arrangement of the sub-pixel units 411 m used in the prior art.
